recommendations! Published in 2024 at "General Relativity and Gravitation"

DOI: 10.1007/s10714-025-03498-8

Abstract: We present a new methodology to explore the morphology of the High Frequency Feature (HFF), i.e., the dominant, rising-frequency GW emission from a proto-neutron star in core-collapse supernovae (CCSNe). We used a residual neural network… read more here.

DOI: 10.1016/j.gca.2017.06.027

Abstract: Abstract Our goal is to compute the abundances of carbon atomic complexes that emerge from the C + O cores of core-collapse supernovae. We utilize our chemical reaction network in which every atomic step of growth employs… read more here.

DOI: 10.1051/0004-6361/202038784

Abstract: Context. In a previous paper we introduced a new method for simulating collisional gravitational N-body systems with linear time scaling on N, based on the Multi-Particle Collision (MPC) approach. This allows us to easily simulate… read more here.

DOI: 10.1088/1402-4896/ad558d

Abstract: We studied the x-ray evolution of the core collapse, Type IIb, supernova SN 2008ax. In addition to the four Swift/XRT observations previously published, we included, for the first time, two observations from XMM-NEWTON to our… read more here.

DOI: 10.1088/1475-7516/2024/05/002

Abstract: The large distances travelled by neutrinos emitted from the Sun and core-collapse supernovae together with the characteristic energy of such neutrinos provide ideal conditions to probe their lifetime, when the decay products evade detection. We… read more here.

DOI: 10.1088/1538-3873/adbf4b

Abstract: Supernovae (SNe) come in various flavors and are classified into different types based on emission and absorption lines in their spectra. SN candidates are now abundant with the advent of large systematic sky surveys like… read more here.

DOI: 10.1093/mnras/staa3607

Abstract: We present measurements of the local core-collapse supernova (CCSN) rate using SN discoveries from the Palomar Transient Factory (PTF). We use a Monte Carlo simulation of hundreds of millions of SN light-curve realizations coupled with… read more here.

DOI: 10.1093/mnras/stab116

Abstract: We present 3D hydrodynamic simulations of neutrino-driven supernovae (SNe) with the PROMETHEUS-HOTB code, evolving the asymmetrically expanding ejecta from shock breakout until they reach the homologous expansion phase after roughly one year. Our calculations continue… read more here.

DOI: 10.1093/mnras/stab1353

Abstract: The analysis of current and future cosmological surveys of Type Ia supernovae (SNe Ia) at high redshift depends on the accurate photometric classification of the SN events detected. Generating realistic simulations of photometric SN surveys… read more here.

recommendations! Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab844

Abstract: Observations have indicated that the pre-stellar core mass function (CMF) is similar to the stellar initial mass function (IMF), except for an offset towards larger masses. This has led to the idea that there is… read more here.
